Summary: Researchers create a transparent graphene-based neural implant offering high-resolution brain activity data from the surface. The implant’s dense array of tiny graphene electrodes enables simultaneous recording of electrical and calcium activity in deep brain layers.
This innovation overcomes previous implant limitations and offers insights for neuroscientific studies. The transparent design allows optical imaging alongside electrical recording, revolutionizing neuroscience research.
Microsoft systems were able to scan through 32 million potential batteries, company says.
Like several scientific discoveries, the researchers stumbled upon this result accidentally while conducting experiments irradiating graphene when they found that irradiated noble gases became trapped between two sheets of graphene, which results in the graphene forming small pockets where the atoms of the gases coalesce into small groups of atoms.
“We used scanning transmission electron microscopy to observe these clusters, and they are really fascinating and a lot of fun to watch,” said Manuel Längle, who is a PhD student at the University of Vienna and lead author of the study. “They rotate, jump, grow and shrink as we image them. Getting the atoms between the layers was the hardest part of the work. Now that we have achieved this, we have a simple system for studying fundamental processes related to material growth and behavior.”
Gate-defined superconducting moiré devices offer high tunability for probing the nature of superconducting and correlated insulating states. Here, the authors report the Little–Parks and Aharonov–Bohm effects in a single gate-defined magic-angle twisted bilayer graphene device.
In an atomically thin stack of semiconductors, a mechanism unseen in any natural substance causes electrons’ spins to align.
The rate at which a raft made of ants is stretched determines its properties because the ants take time to fix holes.
Jan 9 (Reuters) — Microsoft (MSFT.O) has worked with a U.S. national laboratory to use artificial intelligence to rapidly identify a material that could mean producing batteries that require 70% less lithium than now, the company said on Tuesday.
The replacement of much of the lithium with sodium, a common element found in table salt, still needs extensive evaluation by scientists at Pacific Northwest National Laboratory (PNNL) in Richland, Washington to determine whether it will be suitable for mass production.
“Something that could have taken years, we did in two weeks,” Jason Zander, an executive vice president at Microsoft, told Reuters. “That’s the part we’re most excited about. … We just picked one problem. There are thousands of problems to go solve, and it’s applicable to all of them.”
The design solves dendrite-related issues by creating a multilayer battery with diverse materials and managing dendrites by containment.

Advanced Functional Materials, part of the prestigious Advanced portfolio and a top-tier materials science journal, publishes outstanding research across the field.
The process of crystallization fouling is a phenomenon where scale forms on surfaces. It is widespread in nature and technology and affects the energy and water industries. Despite previous attempts, rationally designed surfaces with intrinsic resistance remain elusive due to a lack of understanding of how microfoulants adhere in dynamic aqueous environments.
In a study now published in Science Advances, Julian Schmid and a team of researchers in surface engineering in Switzerland and the U.S. studied the interfacial dynamics of microfoulants by using a micro-scanning fluid dynamic gauge system to demonstrate a rationally developed coating that removes 98% of deposits under shear flow conditions.
